DUMPlNG-WAGO N.

SPECIFICATION forming part of Letters Patent No. 383,930, dated June 5,1888.

Application filed September 26, 1887. Serial No.950fi93. (No model.)

To all whom it may concern.-

Be it known that I, DAVID A. WILLIAMS, a citizen of the United States,residing at Denver, in the county of Arapahoe and State of Colorado,haveinvented certain new and useful Improvements in Dumping-W'agons, ofwhich the following is a specification, reference being had therein tothe accompanying drawings, in which similar letters refer tocorresponding parts.

My invention relates to dumping-wagons; and the object of myimprovements is to provide a self-dumping wagon-box for conveying ore,lime, grave], dirt, or any other material that can be dumped through thebottom of the same, and also a box constructed so that the boardsforming the bottom will not split, and

may be easily and quickly removed and replaced with new ones when wornout or broken.

In the drawings, Figure 1 is a top view of my dumping box; Fig. 2, aside elevation, and Fig.3 an end elevation, of the same. Fig. 4 isasectional view of one corner of my dumping-box, showing the spring forholding the lever. Fig. 5 is asectional end elevation of the box,showing the supporting-bar raised and holding the bottom boards in ahorizontal position, and also showing by dotted lines the bar loweredand the boards dropped on their edges. Fig. 6 is a view of thesupportingstraps, showing the roller attached to same. Fig. 7 is asectional view of one end piece, showing a bottom board when in ahorizontal position and the cast-iron end piece provided with thejournal, the board shown broken off. Fig. 8 is a sectional view of thesame, showing one edge of bottom board, the board being broken off, andalso showing the cast-iron end piece and manner of inserting the end ofthe board in the same. Fig. 9 is an end view of a bottom board, showingplate attached underneath and near the center of the same; and Fig. 10is a sectional view of the bottom board, to which is attached thesupporting-bar, and the manner of attaching the same.

A are the sides of the wagoabox.

B are the end-gates, which may be inserted or removed at pleasure byloosening and tightening rods B, as in other wagon-boxes.

O are the end pieces, in which are journaled the cast-iron end pieces,D, of bottom boards, D, said cast-iron end pieces being provided withjournals D.

E are the supporting-straps, provided with roller E, attached betweenthe lower ends of the same, for supporting the iron supportingbar F, andon which the same slides. Iron supporting-bar F is placed across,underneath, and near the center from end to end of the bottom boards, D,for supporting, raising,and lowering the same. Supportingbar Fisprovided with a loop, F, at one end, said loop being provided with aflattened portion of its lower edge, which rests on roller E when thesupporting-bar is raised to the position shown in Figs. 3 and 5. Saidbar is also provided with pin F", to prevent the same from sliding toofar through the straps E.

To supporting-bar F is attached one of the bottom hoards, D, by means ofattachment D*, so that when said bar is lowered the flattened portion ofloop F is pushed off the roller E, and slides back on thestraight'incline of said loop to the position shown by dotted lines inFig. 5. Bar F is raised or lowered to drop as desired by means ofhand-levtnI, which is attached to front end of rod H. Said rod H isprovided with crank H atits rear extremity, to which is attached theclevis or pieces G, which are also attached to bar F. Rod H is jonrnaledin straps K, which are attached to the sides of the box, as shown inFig. 2.

J is a spring-latch made to retain hand-1e ver I when it is desired tohold the boards D in a horizontal position, and so made that the levermay be easily and quickly detached therefrom when. it is desired to dumpthe load by allowing the bottom boards, D, to turn on their edges, asalso shown by dotted lines in Fig. 5.

D are plates placed on the underside of and between boards D and bar F.

I am aware that dumping-wagons have heretofore been made with the bottomboards pivotedin the longitudinal line of one of their 9 F, providedwithloop F and pin F, supporting-straps E, provided with roller E, ciev isG, attached to said bar F at one extremity and to crank Hof rod H at theother extremity, and rod H, to which is attached hand-lever I, providedwith spring J, as shown and described, and for the purpose set forth.

2. In a dumping-wagon, the combination, with bottom boards, D, providedwith cast-iron end pieces, D, said end pieces being provided withjournals D ofthe supportingbar F, provided with loop F and pin F thesame being supported at one extremity by straps E, provided with rollerE, and attached at the other extremity to hand-lever I by means ofclevis G, and rod H, provided with crank H, said rod H being held inplace by means of straps K, said supportingbar F also being attached -tooneof. the boards D by means of attach-
